Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to an auxiliary device for bending in construction engineering. Background Art

[0002] Under the pressure of the upper or lower die of the bending machine, the metal sheet first undergoes elastic deformation and then enters plastic deformation. At the beginning of plastic bending, the sheet is free to bend. As the upper or lower die applies pressure to the sheet, the sheet and the inner surface of the V-groove of the lower die gradually come close to each other. At the same time, the radius of curvature and the bending arm gradually become smaller. Continue to apply pressure until the stroke ends, so that the upper and lower dies are in full contact with the sheet at three points. At this time, a V-shaped bend is completed, which is commonly known as bending.

[0003] At present, the construction engineering bending devices on the market cannot effectively fix the metal pipes when bending them. After bending, they need to be cut manually. There are position deviations in the manual cutting process, which affects the quality of the finished product and wastes a lot of manpower and material resources.

[0004] For example, a construction engineering bending auxiliary device disclosed in Chinese patent CN218426857U installs a fixing device. When the metal pipe is processed, the adjusting screw handle is adjusted, and the adjusting screw handle rotates to drive the screw rod to move the adjusting clamp. The adjustment and fixing are performed according to the different sizes of the metal pipe to prevent the metal pipe from deviating while being bent, resulting in poor bending effect. The limiting motor works and drives the lead screw so that the cutting motor can move and work smoothly on the lead screw. The cutting motor works and drives the blade to rotate. When the metal pipe is bent, the blade moves and cuts the metal pipe, which saves the time wasted in manual cutting, greatly improves work efficiency, and also ensures the quality of the finished product.

[0005] However, during use of the device, the pipe to be bent needs to be moved to the main frame, thereby increasing the labor intensity of the staff.

[0006] For this reason, we urgently need to provide a kind of construction engineering bending auxiliary device. Utility Model Content
